Annual Well-to-Wheel Emissions By State Shows Growing Strength Of EV Usage
All-electric vehicles don’t emit while driving, but the electricity needed to charge EV batteries do come from power plants. Those power plants in many cases, burn some kind of fuel to produce electricity; however some renewable energy sources don’t take advantage of finite fuels, and thus don’t emit at all.
The Alternative Fuels Data Center has estimated the indirect annual carbon dioxide (CO2) equivalent emissions of a typical EV, using data for 2015.
As it turns out, the well-to-wheel emissions of all-electric vehicles are lower than gasoline vehicles on average in all states:
- gasoline vehicle average: 11,435 pounds of CO2 equivalent
- EV National Average: 4,815 pounds of CO2 equivalent
That said, there is still a huge disproportion of CO2 emission between the states, depending on renewable energy source usage. Vermont for example is almost emission free, while on the other hand coal powered West Virginia stands at 9,451 pounds of CO2 equivalent.
“EVs charging in Vermont are estimated to produce the fewest emissions – oil and gas make up only 1.2% of the electricity sources in the state while cleaner sources such as nuclear, hydro, biomass, wind, and solar make up the rest. West Virginia’s electricity production is 95.7% from coal, making it the state with the most well-to-wheel CO2-equivalent emissions. The national average is 4,815 pounds of CO2-equivalent emissions for a typical EV per year as compared to the average gasoline-powered car which produces 11,435 pounds of CO2-equivalent emissions annually.”
The most important thing is that the switch is on to plug-in vehicles, and at the same time, every year’s electricity production becomes a little greener, so every EV sold will help the environment a little more every day.
